[Generalized seizures as onset of Gitelman's syndrome].

Gitelman's syndrome is a rare autosomal recessive syndrome presenting with hypocalciuria, hypomagnesiemia and hypokalemic metabolic alkalosis. This case reports a patient admitted with generalized seizures with the above-mentioned biochemical abnormalities, thus representing a rare onset of Gitelman's syndrome which - to our knowledge - has not been described previously. The patient had a homozygote deletion of the CLC-KB gene, CLCNKB. The case was successfully treated by correcting hypokalemia and hypomagnesiemia with supplemental potassium and magnesium.
